Rick, what you say is not unthought of by many and it's more frightening than thinking that they were just not too good at investigating or deducing. I think another possible explanation comes under the heading of "Nah...can't be."The reality of what they were seeing was simply too incredulous to be assimilated. At the time, Oswald was the likely suspect and all protestations to the contrary simply didn't fit. I mean they may have fit the crime, but not the perceived circumstances. Some things that the conspiracy believers have thought, have also been disproved over the years so it's easy to see how the trail was traced in the Warren Report.
For instance, it was a longtime bulwark of the conspiracy theorists that one bullet could not have gone through both bodies without doing odd twists and turns and changing direction. This has been explained through computer modeling and precise timing locating of the positions of Connelly and Kennedy. On the other hand it does make the condition of Magic Bullet even more ridiculous and show it to be a "plant." Who would have planted it though and again why didn't we investigate that. Possibly because it simply was an explanation that worked at the time? I dunno'.............
I don't think that anyone was some mysterious "X" that knew all the answers. I doubt that any "X" came to the commission either. But I still think that for every 5 pieces that fit, one piece didn't, and it was easier to make the piece fit than to continue to investigate. None of this excuses the gawdawful and slipshod investigation that took place when the case was reopened under the committee to look into past assasinations....that was a bigger joke.
Future generations may find out, but will they believe.....or have we played the game so long that we will never know what to believe? Was Oswald any more than just a patsy? Ruby? The autopsy was still a disaster that we can never replicate. Too many people unaccounted for.........I would have hoped that any of us sitting on the original commission would have had more sense and more courage......but it's simply a hope. Fun to speculate.
